SPECIFICATION forming part of Letters Patent No. 520,450, dated May 29,1894. A plication filedNovember 29, 1893- fierial No. 492,363. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE W. PERO, a citizen of the United States, anda resident of West New Brighton, in the county of Richmond and State ofNew York, have invented certain new and useful Improvements in Axle-Lubricators, of which the following is a specification.

My invention has for its main object to provide means for economicallyand efiectively lubricating the journals of car axles, and to this endconsists first in combining with an oiling disk a self-adjusting scraperor wiper to prevent an undue or excessive supply of lubricating materialto the journal; and secondly, in certain details of construction andcombinations of devices, all of which will be hereinafter more fullydescribed and particularly pointed out in the appended claims.

In the accompanying drawings, Figure l is a vertical sectional viewtaken at the line y, y of Fig. 2. Fig. 2 is a vertical sectional Viewtaken at the line w, w of Fig. 1; and Fig. 3 is aplan View of thelubricating means removed from the axle box and of the scraper or wiperdetached.

In the several views the same parts will be found designated by the samenumerals of reference.

v1 designates the car axle journal box of about the usual construction;2 a part of the car axle, and 3 the axle journal arranged to rotate insaid axle box, which, as customary, is provided on its upper side with abrass or bearing 4, for the journal.

At the bottom of the box beneath the journal, I place my novel means forlubricating the latter, andI shall now more fully describe the detailsof the same.

5 designates as an entirety, a support, which is composed of twoend-bars 6, 6, and atransverse connecting bar 7, all preferably cast inone piece. The inner ends of the bars 6 are preferably curved upwardly,as shown, to enable the ready insertion of the support within the box.

Extending outwardly from the cross bar and parallel with the side bars6, is an elongated pivot-pin 7, upon which is mounted a lever or frame8, comprising two parallel upwardly-extending arms 9, 9, having each avertical slot or fork l0, and an arm 11 bearing at its outer end anupwardly-extending weight 12. The arms 9, 9 are arranged on one side ofthe pivot hole, and the arm 11 is arranged on the other side thereof.The slots or forks 10 receive journals or studs 13 projecting fromopposite sides of a sheet-metal disk or thin wheel 14, which revolves inthe space 15 between the arms 9, and which may be provided with washers16 between said arms.

On the upper side of the lever-frame 8 is a projection 17, which isperforated parallel with the disk journals to receive a hinge-pin 18,that passes through eyes 19 formed at one end of a scraper or wiper 20,which is bifurcated at 21 to straddle the projection 17 and enable itsperforation and the eyes 19 to be brought into alignment for the passagetherethrough of the hinge-pin 18. The scraper or wiper is preferablymade of sheet-metal and provided with a slot 22, through which theuppermost portion of the disk projects and which enables the scraper orwiper to rest or bear upon the periphery of the disk, at the ends 23 and24 of the slot. The scraper or wiper is made comparatively widepreferably, and from the end 23 of the slot is curved downwardly toterminate near the bottom of the disk.

The pivot pin 7 is elongated or extended forward a considerable distanceto enable the disk-carrying frame to be conveniently mounted andremoved, when the support 6 is in position in the axle-box. Thedisk-carrying frame being located or arranged back near to the cross-bar7, it would be quite inconvenient to place it in position while thesupport is in the axle-box if the pivot pin were made short or only longenough to hold said frame. After the lever-frame has been put upon thepivot pin a sleeve 25 may be slipped upon the latter to hold the framein place, and said sleeve may be kept in position by a cotter pin 26passing through a hole at or near the outer end of the pivot'pin.

At Figs. 1 and 2 the contrivance is shown in a working position andcondition. At the bottom of the axle-box is shown at 27 a lubricatingmaterial, preferably oil, but of course it will be understood that thismaterial may be contained in a cup or other vessel placed within theaxle-box.

In operation, the disk, running in contact with the axle journal, isrotated thereby and running through the lubricating material carries upthe same and supplies it to the journal. The action of the disk is suchas to carry up to the journal a quantity of oil largely in excess ofwhat is needed, but this action is overcome or cured by reason of thepresence of the device 20, which operates to effectually regulate thesupply of oil to the journal, the ends 23 and 24 of the slot (in contactwith whichthe periphery of the disk runs) serving to scrape or wipe fromthe periphery of the disk any excess of oil and to cause the same tofallback to the reservoir; and the body of the scraper or wiper servingat'the same time as a hood .or deflector to intercept and return any oilwhich may splash or be thrown off from the disk by centrifugal force.When the disk turns in the direction of the arrow at Fig. 1, the end 23of the slot serves as the wiperor scraper, and when the disk rotates inthe opposite direction the end 24 of the slot serves as the wiper orscraper. The device 20 is so pivoted as that by gravity the ends of theslot rest always on the periphery of the disk.

If it should bedesired at any time to remove the disk, on account ofwear or for any other reason, and substitute another disk therefor, thismay be speedily accomplished by throwing back the device 20, lifting theold disk from its bearings, dropping the new one into place, and thenreturning the scraper to its working position.

It will be observed that the weight 12 tends to automatically keep thedisk always in contact with the axle journal and hence to keep thelatter supplied with oil after the brasses '4 become worn, as well as atthe start, when they are new. In other words, the disk is so mounted asto automatically adjust itself to the journal not only when it maybecome worn, but also when the brasses or journal bearings may becomeworn. This capacity of the disk to always keep in contact with thejournal, and the provision of means for preventing an excessive supplyof oil to the journal constitute the main features of my invention. Itwill of course be understood that in consequence of the constant contactof the disk with the journal, the latter will be always supplied withoil, as long as the periphery of the disk passes therethrough; and itwill also be understood that by reason of the presence of the regulator20, only the needed quantity of oil .is supplied to the journal, thusnot merely greatly economizing in oil but also enabling the journal torun a much greater length of time than would be possible if some meanswere not provided for controlling the tendency or action of the disk tocarry or feed an excessive quantity of the lubricant to the journal.

The scraper, wiper or regulator may of course be differently constructedand arranged without departing from the spirit of this part ofmyinvention. In addition to the functions already referred to, thisdevice also serves the useful office of preventing dust, dirt, or grit,being carried up to the journal by the disk.

Various changes in detail construction and arrangement, as for examplethe substitution of a spring for the weight, may be made withoutdeparting from the gist of my several improvements.

7 The contrivance may be used elsewhere than in car-axle boxes.

What I claim as new, and desire to secure by Letters Patent, is

1. In an axle lubricator, the combination of a journal, apivotallymounted frame weighted on one side of its pivot and carrying onthe opposite side an oiling disk, and a self-adjusting scraper or wiperfor removing surplus oil from said disk.

2. In an axle lubricator, the combination of a journal, apivotallymounted frame weighted on one side of its pivot and carrying anoiling disk on the other side thereof, and a scraper or wiper for saiddisk hinged to or upon said frame and adapted to maintain always itsproper relative position to said disk when wear occurs, as well as whenthe disk is moved bodily in any direction.

3. In an axle lubricator, the combination of a journal, an oiling disk,and a hinged scraper or wiper provided with a slot through which theupper portion of the disk protrudes and upon the periphery of which diskthe ends of the slot always bear.
